Objective: to study the UTI-causing bacteria frequency and sensitivity profiles in a teaching hospital in northeastern Brazil. Method: A retrospective cross-sectional study was conducted based on the review of 279 patients for whom uroculture and urinary catheter cultures were routinely processed in the Microbiology Laboratory of Sao Vicente de Paulo Hospital. Results: For the catheter culture group, the most frequent microorganism was Staphylococcus epidermidis (47%), while in urine culture group Escherichia coli was the microorganism most frequently isolated (52%). E. coli showed 76.46%, 70%, and 86.36% resistance to ampicillin, amoxicillin and Sulfamethoxazole/trimethoprim respectively. S. epidermidis showed high resistance to most drugs used, demonstrating that these drugs should not be used to treat UTIs in this institution. Conclusion: This study represents the first study evaluating bacterial resistance in this institution and since data involving epidemiological surveillance and microbiological are limited in this region and due to its importance in the national context, the results may reflect important information to the body of research/data on bacterial resistance in the world.
